Master Password

Hello,
I'm selling an iMac G4 and I'm trying to remove the master password. Here's what I'm doing.
Under the security preferences next to "A master password is set for this computer" I click "change". I then enter my current password but leave the new password field and the verify field blank. I press enter and get the message "You did not enter a master password, to enable filevault you must have a master password". However, I do not have filevault enabled and I don't wish to enable it. I just want to get rid of the master password.
Does anyone know if there is a way to do this?
I know I can just set a generic password and pass it along to the new owner, but it would be easier for them, I think, if the master password was just blank.
Thanks,
Greg

Hey,
Thanks anyway folks, after more digging I found this.
"If you are not using File Vault and do not have any other users on your computer using it, you can delete the master password keychain file. As an administrator go to /Library/Keychains/ and delete the FileVaultMaster.keychain by dragging it to the trash. Mac OS X will then assume no master password is set.

How do i reset my master password on MacBook Pro previously owned by someone else?

I purchased from someone else in 2011 and needed to reset master password. It was done, but now I am having problems resetting it. It does not recognize the reset password. I am trying to add new software and can't do so without password. Can someone please help me? I entered to change in terminal window, but when it comes to adding new password, computer won't allow to add new passcode in blank.

Master Password Feature: After sometime (10-15 min.) the drop down list for the field on any site does not show; opening new window (not refresh or new tab) drop down appears.?

I manage a ton of accounts for different customers suing the same login pages (GoDaddy, WordPress, etc.) I use the Master Password Feature to help keep track of the many variants in logins and passwords.
After some unknown period of time, even closing the page tab so a new page session is started at the remote server, Firefox does not provide me with the usual drop-down selection list of the previously used login names. However, if I open a new FF window (file/new window) from the menu bar, the drop down becomes available.
How can I refresh the original window session in FF or change the timeout length?

Well, you said LOV...that might mean you are using JDev 11g. Are you? If so what technology stack are you using?
Assuming you are using JSF (?) you might be "backing" your list component in the application scope...but that is not likely.
If you are using ADF/BC on your business component level, you can clear your view object from which you are querying the possible values of this list...unless your you have made a method to compile this list...in which case you know what you are doing...so that is probably not the case.
Essentially you want to requery the VO upon which your LOV is based...unless you are using JPA or something...and then I know "requery" is not the right word...is it?

Please help me get my laptop back someone has cracked the master password and is running multiple operating systems which I have no access to

Okay so I am not a computer expert by any means and have no clue how to fix my system. My father worked for intel for over 20 years as an engineer I asked him to restore my laptop to its original factory state and instead he cracked the master password
installed multiple operating systems and made himself the administrator or domain controller. Many features and options I do not have access to so reading the trouble shooting and going through the steps always leads me to a dead end. The laptop is TOSHIBA
SATELLITE L875D-S7332 a6 VISION AMD WINDOWS 8. As far as I can see my profile is actual running a version of windows 7. I do see reference to a windows 8RT windows 2003 windows vista wow64 and 32 I don't know what all that means I would just like to know how
wipe everything and get back to the factory condition I bought it in. If anyone can help it would be much appreciated

Do you have Win 7 installation disk? If yes, then go ahead and format the laptop if you don't need any data. If you need the data it it, then copy the same to USB disk and format it. Removing OS and deleting these things will anyhow keep some remains on
HDD. TO get the speed and performance back, you might need a fresh installation.

You can reset the master password and go from there:
For Snow Leopard and earlier:
http://support.apple.com/kb/HT1274?viewlocale=en_US&locale=en_US
For Lion and later:
https://discussions.apple.com/docs/DOC-4101
On your phone, if you connect it to the computer with a USB cable, it should show up as an external drive in Finder. From there you should be able to navigate to your pictures folder and copy your stuff.

When I go to a website requiring login, and am logged in automatically, I still get prompted by Software Security Defice for master password. New w/Firefox 24.

If I go to a website that requires a login & password, and I have it set up to automatically log me in, I get automatically logged in (it remembers by userid & password for that site), but the prompt from the Software Security Device for my master password appears as well. I can cancel the prompt and it goes away, but it shouldn't show up because I'm already logged in. This problem started happening after I downloaded Firefox 24 yesterday.

Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Firefox/Tools > Add-ons > Appearance).
*Do NOT click the Reset button on the Safe Mode start window.

Note that Firefox Sync also requires you to enter the Master Password.

I have a Mac leopard. Did a recent recommended update. When it finished,I restarted then a window came up to enter Master Password. I don't know what it is and when I try to enter one, the window shakes so I am unable to use computer at all.

Please confirm exactly what Mac this is, and what 'recent update' you installed.

Id appreciate any help, thanx in advance.

Insert the install disk that came with your Mac, restart the Mac, and hold down the "c" key until you see the "spinning gear" boot icon.

Is there a way to use a Master Password only to view Saved Passwords, without having to type it in every session?

If anyone ever uses my computer, they can easily see my Saved Passwords. I want to be able to secure them. The only way to do that is by setting a Master Password, which is great, but I don't really want to have to type it in every time I open up my web browser.
I couldn't seem to find this anywhere in any searches. Is there an Add-on or tweak that can set a Master Password only to protect my Saved Passwords?

Thanks, Matt. In my case, the monitor definitely shuts off when I unplug the power from my laptop in clamshell mode. If the lid is open, however, the monitor continues to function even without the power adapter plugged into my laptop. Ideally, I'd like to have the lid closed on my laptop and be able to use the external monitor without having the power plugged into my laptop. That's what doesn't seem to work - if your does, please let me know if you have any pointers.
Thanks again!

Don't know my Master Password.

When I upgraded my white 2008 MacBook to OS 10.6.8, the new OS forced me to chose a new administrator password; apparently the old one wasn't strong enough. Today I installed software updates that required restarting the computer, and I couldn't remember my new admin password. I tried to change it to a new one that I could remember, but to do that I had to provide a "Master Password". After much trial and error, I finally remembered my adminstrator password and got into my account. I don't remember creating a master password, and if I did, I didn't write it down anyplace that I can find it. Silly me, I keep some passwords in a file on the computer, but the master password isn't one of them. What is the master password; where is it; and how can I recover it in case I need it again? I've read several threads relating to this issue, but they all seem to refer to something called File Vault. I can't find File Vault on my computer, so this master password apparently doesn't have anything to do with that. If I can't remember either the administrator password or the master password, has my MacBook just become an expensive paperweight?

I haven't used my desktop iMac in a long time and can't get pass the opening login...I thought I remembered my password, but, apparently not. How do I change it. I don't THINK I have a "master password" on the thing. I've never used one on any of

I haven't used my IMac in a long time and went to boot it up, and I find I don't remember the correct username and password (I use several computers..I try to keep the passwords similar, with a number for the chronological order in which I started using them) I've tried all the others I use for passwords. The 'hint" keeps coming up for the password I am pretty sure is the correct one, but, still cannot get in. I also don't remember whether I changed my surname on the computer...it was changed legally a little while ago, but some of my older devices still have my birth-name in there)
HELP
I don't think I ever set up a "master password" on the thing...I never use those. I am the only person with access to my personal devices.
thanks

I tried to set up a new account but it has a master password and do not recall setting one how do I change that it will not let me turn it off without knowing the password I do not recall ever setting on. How do I clear the Master Password?

I was trying to set up my mobile phone with Android with the Firefox App and my Netbook which I use the Firefox on and sync them but it came up that I have a Master Password but I do not recall setting one up and I have record of all my passwords that I keep in a secure place and I had trouble with a hacker who had accessed several of my accounts and I am now concerned that they may have also access this and we did not catch this one as we did the other accounts and stopped them from getting access. But that is not my concern any longer as that has been remedied the problem is how do I get the password unlocked or changed since I have no idea what it is? I tried to turn it off but it will not allow me to do that either without knowing it. Please advise as to what can be done so I can use this App on my Droid. Thanks. Deborah

I use master password & if I change passwords on a site, it doesn't ask to "change" Also doesn't ask to "remember" with new usernames/passwords. Does anyone know how to fix this or add usernames & passwords to saved password page on Firefox.

Firefox (I think version 5, maybe 4) does not ask to "remember" passwords anymore nor does it ask to "change" a password when I've done that. It didn't ask when I changed my Facebook password & I have to log in each time so I removed my username & password for FB on Firefox's "saved password" page. When I've don't that before, it asks to "remember" but doesn't anymore. I use a master password.

Make sure that you do not run Firefox in permanent Private Browsing mode.

You can remove autocomplete=off with a bookmarklet to make Firefox save the name and password.

How do I actually use a master password?

My home folder is protected with file vault and so I have a master password set. If ever I should forget my user password how would I use the master password to get in to my Mac?
thx

If you would ever forget your password, then you
would need to use the Mac OS X Install Discs to reset your password.
The above suggestion is not correct for an account that's protected with FileVault. Even if it does allow you to reset the password on the account it does not reset the password on the encrypted home folder.
Instead read this Apple Support article.
Basically you "attempt" to logon to the account using incorrect passwords. After three incorrect attempts you'll be prompted for the Master Password (or if the account has a password hint set you'll see the password hint - enter another incorrect password to get the Master Password prompt).
At this point you can enter the Master Password and you'll be allowed to set a new password for the account. This will also set the new password on the encrypted home folder, mount it and log you in to the account.
You can also mount a FileVault encrypted home folder from the command line with the Master Password using hdiutil. One reason you might want to do this is if you had multiple accounts on a machine and you were logged in to one account but needed to recover or access files in an encrypted home folder of another account.

How do you re-set the master password without knowing what it is?

I set up a master password, and can't remember it. I haven't activated the filevault, so from what I read, that is good. But I still don't know how to re-set the master password if I don't have the old one to change it. Please help. I have too many albums in iTunes, documents, and calander events that have not been backed up, so I don't want to reinstall the software, if that is an option. At least not until I can pick up an external backup.

I forget where I read this, but to eliminate an existing filevault "master password", delete the files 'FileVaultMaster.cer' and 'FileVaultMaster.keychain' in your computer's main '/Library/Keychains/' folder (not through "Keychain Access.app"). You should then be able to set a new "master password" in the "Security" preference pane if you ever decide to use "filevault" again. Note that if you do this while an account is still encrypted (ie. with filevault enabled), that account will not be accessible with the new "master password".

Forgot Master Password, no acct File Vault: How to get rid of Mst Password?

Hi -
I am embarrassed, mortified, and humbled about having to post this because it's not about 'someone I know' but about something careless that I did.
This morning, I set up a second account with File Vault on my MBA (Late 2010) to keep sensitive files in it. While setting it up, I set a Master Password which I hadn't enabled before this morning. I used the password generator and used one that I dutifully copied on the clipboard with the intention of IMMEDIATELY copying it into my 1Password app. Then I set up the second account with File Vault.
Well, of course, something distracted me, I habitually copied something else on the clipboard, and I lost the Master Password from my clipboard. (I know, I've been kicking myself ever since...)
Here's my question: The Master Password is not protecting any content in File Vault and I would like to disable the forgotten Master Password and set up one that I really will remember (at least, that's the plan!). How can I do this?
I deleted the new account and I have only one other which is the primary administrator account that is not protected by File Vault. Thanks in advance for any help on this!

*How to reset FileVault master password*
http://discussions.apple.com/thread.jspa?messageID=5822772
As explained there, and for obvious security reasons, a new master password created in this fashion way will not unlock any pre-existing FileVault accounts. So resetting the master password is only useful after you have turned off FileVault in all existing accounts, as is true in your case.
